Australia moved to the top of Pool A as they ran in 11 tries in a mammoth 65-3 win over Uruguay in their second Rugby World Cup match this afternoon.

It took them just seven minutes to take lead, as the power of their forwards pushed Uruguay back before Sean McMahon escaped with the ball to score a simple try.

Almost immediately from kickoff Joseph Tomane grabbed Australia's second try, with Quade Cooper kicking the extras.

Cooper was then sent to the sin bin in the 15th minute and Felipe Berchesi took advantage of his misdirection to kick three points for Uruguay.

However, Australia then began to assert their dominance, with Dean Mumm scoring a simple try before Henry Speight made sure of the bonus point with a try of his own.

In the 36th minute, Ben McCalman scored under the posts and Cooper kicked an easy conversion to give Australia a comfortable half-time lead.

Drew Mitchell then ran in two tries in quick succession to to make it 41-3, but Cooper missed both conversions.

McCalman registered his second try of the afternoon in the 61st minute before McMahon got his second after more powerful forward play.

Matt Toomua notched another try with a few minutes remaining and Tevita Kuridrani put the icing on the cake with the final play of the game.

Cooper kicked the extras, but question marks will circle his performance after the fly-half was sin-binned and missed five of his 11 conversions.
